Understood. I wasn’t clear. The higher end fords/rams have a ton more sound deadening in them. Iirc a XL model will be about 1200#s lighter than a lariat trim level.
I was also disappointed in the noise in the f550. But that 10 speed transmission was sooo nice.
sound deadening is desperately needed on Ford XLT/ Ram SLT. Google sound deadening showdown. They make great stuff. Start with the seals on the bottom of the doors and the wall behind the rear seat. Most of your noise is coming thru there.
love the build. I’m dreaming of a similar set up.
